throttle issues

[trelex03]

Ok so my 93 standard Ls is having throttle problems.. starting off, takes forever to even get to speed, then if i manage to make it to 5th gear i can step on the pedal till it hits the bottom but it doesnt go more then 65-75..
Any ideas what could be causing the problem?
I changed the idle air control already

Check engine lights? Smoke? Try a compression and leakdown test. Any recent work done to the car?

No work, only new things on it really are
Distributor
Idle air control
Ignition switch


Those r about it really... Uncle ran the codes and it says either 2 things could be possibly wrong.. the idle air control, or there could be a malfunction with the distributor internals. So we have warrenty on the dist, gunna replace that n.give that a try..

The distributor could be bad and the rotor might not make good contact with the tabs. Do you have the firing order correct?

Also check your throttle cable and see if it's got to much slack.

Throttle positioning sensor?

do your rpms go really high while your trying to get to speed.

Thinking maybe it might b something with the throttle body or sensors? Maybe the fuel injectors?

Could be the TPS.

Try cleaning your IACV and see if that helps
